Switching from auto to stick really does not seem hard. Here I will list the parts of an manual tranny. And functions of a manual trans compaired to auto,
If you notice with many car designs they are all the same. Same chassis same body same interior, take the kia sephia for example. From the car manufacture where they build the cars they make a handful of auto and a hand full of manuals. To limit cost and more cost effective they keep the car the same as in body wise every car has the same shape then the engine is put into place with either a manual tranny or automatic. Then it gets shipped and put onto a boat with the chassis, engine body and color and tires realistically interior is never been established , when the car gets off the boat then they establish the interior or as dealers like to call it “packages” some have leather and some have cloth some have air some don’t. This is why it is very cheep to ship the car with nothing in it and dealers buy hundreds,
Every car is built the same, but different “packages”, if you notice when your installing a sound system in your auto car with 4guage wires and an amp and subs , you want to look for an opening in the firewall,
If you take away the carpet there are drilled out holes and spots and something non metal to cover/fill these in. you scratch ur head and wonder what the **** but gives u a place to feed this wire through(these holes are patched so heat does not come in the compartment to suffocate the driver) these patches you notice is where a manual tranny /clutch pedal would go. Interesting, also what is interesting is your center consol where u see the p n d 2 1, that’s automatic in a manual car this is different there is a shift boot instead
NOW what if you completely removed the automatic transmission and the inside middle consol, you now have just an engine with a missing transmission,
Now manual trannys use a flywheel, clutch disk, pressure plate release bearing release fork clutch housing/studs, in an automatic car its totally different, autos have a cover plate, Flex plate(where the flywheel would go and a torque converter(clutch) but that’s not important what is important is automatic uses oil pressure with the tq converter that makes it automatically shift with the speed/sensors, and pressure calculated by the computer to turn on or off the solenoids to shift the car, in a manual you would never need such crap. In a manual car especially newer ones use what is called a hydraulic clutch, its the same principal as your breaks work. A master cylinder is connected to the clutch pedal, when pressed it transmits fluids to the clutch slave cylinder to move the release lever at the clutch, no what happens when u press that pedal its stuck, what how can that be, well on the slave cylinder there is a return spring to shift back the fluid and allow the pedal to be pressed in again now one u got that u can press in the clutch all day what! when does it get to do something, when you add in the transmission gears. Now you are able to shift gears all day long and not go anywhere.
Think about a bus/ huge truck they have what is called a drive shaft its long and huge and spins to another gear(rear wheel drive called the wheel differential to spin the tires)
In Front wheel drive cars this is the same concept just minus that long shaftfrom the transmission, the differential is connected to the output gear in the manual tranny just like the automatic. Just the difference is design; manual trannys do not look like the automatic ones. The differential is a bunch of gears to allow the wheels to turn at different speeds when rounding corners, now a transaxle is now connected to the differential and the transaxle is then connected to cv joints and axel and to the wheel. Where Now the power of shifting and moving can be achieved.
NOW THE PROBLEMS
You have everything in place and driving the car, you notice your engine light and many other lights come on to indicate to you that hey you got a problem. But you don’t, why is that, well in an automatic car(which is my problem with the kia sephia 2000, you have a TCC (torque converter control) , the computer controls the tcc solenoid in response to signals from the computer as in pressure and tells the automatic trans to shift based on pressure, the pressure in a transmission is about 500psi at start up, and reverse, and the cpu is registering 0psi hence its thinking it stalled and may or might not affect the rest of the sensors (mass air glow) vacuum, valve timing, gas that’s connect to the computer.
So bottom line is that you are going to have to change out that computer as well to one that fits a manual car
Parts are cheep go to a junkyard find the same year and yank out the pedals hydraulic system clutches flywheels and transaxle and differential now paying a mechanic to do it ha good luck. Unless you own your own lift that costs 12-22 thousand then leave it as is. Or if you have all the tools to yank out an engine and tranny and the tools to do it yourself go ahead but paying a mechanic would be ridicules bc he makes 25 bucks flat rate hour and what if the job takes 72h 1800 just on labor alone plus the estimate of 1500 you spent on the manual tranny with all the parts plus computer , estimate job completed total 3300 to transfer, yea you can sell you auto tranny and cut some of that loses about 1/4th but this is not for someone with high bills every month and a income of 2000 per month, will take you forever to get to your goal, something else to consider is to buy another kia sephia 2000 manual for 300 bucks that has been a total wreak and just take out the damaged metal and replace it with the mint condition automatic one and basically use the automatic as parts to fix the manuel, but then again getting a mechanic to do all that , **** that
